DUMPING BODY.

Application filed December 28, 1927. Serial No. 243,085.

This invention relates to dumping bodies and more particularly to a control mechanism for use in connection with the dumping bodies of vehicles, which may be employed with 5 dumping bodies of the manually controlled type to secure the same in a desired adjusted position.

A further object of the invention is to provide means for controlling manual operation of a dumping body mechanism of such character that the body may be locked in any desired adjusted position.

A. still further object of the invention is the provision of a manually controllable dumping body which shifts longitudinally as it tilts and in which the power required for the dumping operation is materially reduced, by reason of a construction permitting the use of longitudinally shifting pivots therefor.

A still further object of the invention is to provide a construction of this character hav ing control means such that movement of the body in at least one direction may be by gravity.

A still further object of the invention is the provision of a construction of this character 7 wherein the control mechanism will act to lock the body in any adjusted position.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a side elevation of dumping body and control'mechanism constructed in accordance with the present invention;

Referring now more particularly to the drawings, the numeral 10 indicates a subframe and 11 a body mounted for oscillation thereon. This body is connected with the frame by mechanism constructed in accord ance with the directions of my prior applica tion, No. 236,278, filed November 28, 1927, for dumping bodies. In the construction referred to, I have illustrated the body as equipped with two rollers 12 and 13 alternately acting as pivots about which the weight of the body shifts and coacting with a cam track 14: in such manner that during tilting of the body the body is longitudinally shifted. The connections of the pivot elements with the body are made in such fashion that the body must be forcibly shifted to its dumping position and may return by gravity to its loading position. Attention is directed to the fact that due to the successive engagement of the pivot rollers 12 and 13 with the cam track, the pressure required to shift the body to its dumping posit-ion is reduced to a minimum.

The frame 10 is illustrated as equipped with mounting brackets 15 having mounted therein shafts 16, 17 and 18. The shaft 16 has mounted thereon a segment gear 19 having rigidly secured thereto an arm 20, which is link-connected with the body, as at 21, so

that as the body is oscillated, the arm 20 and segment 19 will be rocked, or vice versa.

The shaft 17 has secured thereto a combined unit including a pinion 22meshing with the segment 19 and a gear 23. The shaft 18 has secured thereto a pinion 2 1 meshing with the gear 23. It will be obvious that by rotation of the shaft 18, the body will be oscillated and by oscillation of the body, the shaft 18 will be rotated. The structure so far described has been of elements either well known in the art or described in my prior application above identified.

In accordance with the present invention, one end of the shaft 18 is extended through a bracket 15 to one side of the frame, which has mounted thereon a bearing bracket through which the shaft is extended. Rotatable upon this end of the shaft is mounted a plate 26, the inner face of which is provided with teeth 27. Pivotcd to the bracket at 28 is a lever 29, one end of which forms a dog 30, which may be moved into or out of engagement with the teeth to lock the plate against rotation. A spring 31 holds the lever 29 either in operative or inoperative position. Keyed to the shaf 18 outwardly of the plate 26 is a disk 32, the periphery of which is provided with outwardly extending lugs 33, at present shown as three in number. llhe end of the shaft 18 is rotatably engaged in the bore 3 1- of a control plate 35, which has projecting from the inner face thereof trip lugs 36 corresponding in number to the lugs no of the dislt 32 and of less width than the space between adjacent faces of the lugs 33. The plate 26 has a flange 37 surrounding the disl: 32 and control plate 35, and has seemed to the end of this flange a washer plate 258 engaging the outer face of the control plate 35 and preventing separation of this control plate and the plate :26.

The control plate 35 has keyed thereto a. stub shaft 39, the outer end of which has extended therethrough a pin l-O. llotatable upon the stub sia'tt outwardly of the plate 35 is a casting 41, the out-er end of which is notched at 4-2 for coaetion with the pin. This casting provides a mounting for a handle l3, by means of which it may be rotated. The periphery of the disk 32 adjacent the notches is recessed, indicated at 4. L, the recesses decreasing in depth away from the adjacent lug. Each recess has mounted therein a roller 1%., which is of such size that when it is disposed adjacent the lug, it has no contactwith the inner face of the flange 37. Springs 45, however, carried by each lug 33 serve to urge these rollers away from the lugs so that they come into clam ing engagement between the flange and the peripheral wall of the disk. It will be seen that the disk 32 and plate 37 with their associated elements combine to produce a clutch mechanism, locking these elements to one another. If an attempt is made to rotate the disk 32 in one direction, one set of the rollers will. recede toward their lugs but the other set of the rollers will act to clamp the disk against rotation. The lugs 56, however, serve as a means for releasing a desired. set of rollers. it will be obvious that if the handle casting is shifted to engage with the pin 40 and the handle rotated, the lugs 36 will come into ongageu'ient with the rollers at corresponding sides of the lugs 33. As the rollers at the opposite sides will, in response to movement of the disk in this direction, be automatically released, the disl: 32'

and accordingly the shaft 18 will be rotated.

Immediately upon release of the handle, the springs will force the rollers outwardly in the recesses, causing; clamping engagement between the flange 37 and the dish. If, at this time, the plate 26 is held against rotation by engagement therewith of the dog 30, the shaft 18 will be locked.

in conjunction with apparatus of this character, it is desirable that a latching means he runployed for holding the body in loading or transporting position to relieve the roller clutch mechanism of the strain which would otherwise be imposed thereon. In the present instance, the body has been shown as provided at. its forward end with a prop d6 adapted to seat upon a transverse support ll. This support has an opening formed therein and a bar 48 is mounted in guides 49 for longitudinal shifting and rotating movements and in such fashion that it is aligned with the opening when the prop is seated upon the suppo t. A spring 50 constantly urges the bar inwar'lly for engagement in the opening of the prop, and the outer end of the bar is provided with an angular portion 51 serving as a handle, by means of which it may be withdrawn against the spring or rotated. The outermost guide 49 has an abutment 52, and upon the shaft is a lug 53. This lug, by engagement with the guide, limits the inward movement of the bar 48 under the influence of the spring with the bar sufficiently advanced to engage in the opening of the prep 4?). ll hen the bar is withdrawn, this lug may be positioned by rotation of the bar to engage the abutment 52, holding; the bar against longitudinal movement by the sp "ing' with the bar sufficiently withdrawn to release the body.

In operation of the device as above described and assuming the body to. be in the position illustrated, if it is desired to employ the body in its automatic capacity, it is simply necessary for the operator, after releasing the latch bar 48, to swing the lever 29 to the position where the dog 30 disengagcs from the teeth 27 of the plate 26. The

bony will then be released for movement and will oscillate to its dumping position in its movements, causing the arm 20 to rock, thereby causing rotation of the shaft 18 and through the disk 32 and control plate 35 rotation of the stub shaft 39 and the plate 26. When the operation has been completed, the body canv be locked against return movement by re-engaging the dog 30 with the teeth of the plate 26. As the rollers R i t this time lock the plate and dislr against relative rir tation and the plate 26 is locked against rotation, the shaft 18 may not rotate and accordingly the gear t "am and body are held stationary. Return movement is accomplished in the same manner. If desired, the body may be positively shifted to insure proper positioning thereof by engaging the crank and rotati the same through short space. lVhen the handle is released, t-l e rollers will immediately serve to loclr the parts in position and engagement of the latch bar may be ery readily accomplished.

To operate the device manually, the dog 30 is left engaged and the handle is engaged with the stub shaft'39 and rotated. The lugs 36 engage against the set of rollers which would normally be effective to .prevent rotation of the shaft 18 in the direction in which the handle and shaft 39' are being rotated and force them toward the lugs The other set of rollers will automatically recede against their springs to permit rotation of the shaft 18. VJhen the body has reached its desired position, it is merely necessary to disengage the handle when the rollers will immediately become effective to lock the shaft 18 and thus prevent further movement of the body in either direction.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter claimed.
